I build fast, polished, AI-powered web applications, from SaaS dashboards to AI chat and agent features, shipped end to end and built to scale. With 5+ years in React and Next.js, I work closely with product and design teams to turn ideas into interfaces that are responsive, accessible, and genuinely fast. I ask questions before I write code because I want to understand the why behind a feature, not just the ticket. Recent build: Founding frontend engineer on Flolyt, an AI-powered customer engagement platform for B2C/DTC brands. Built the Dashboard, Customer Intelligence, Segmentation, Campaign Workflows, and Analytics modules from scratch, plus an AI Workflow Studio that turns a plain-English prompt into a live running campaign. Real production data, real users, real stakes. What I ship: ✅ Production-grade frontends in React, Next.js (SSR/SSG), and TypeScript — clean, tested, maintainable code ✅ AI-powered features using the OpenAI API and other LLM APIs: chat UIs, prompt-to-workflow tools, and agent integrations ✅ Pixel-perfect, fully responsive UI with Tailwind CSS, shadcn/ui, and Radix UI ✅ Performance optimization for Core Web Vitals: lazy loading, render and bundle optimization ✅ Accessible, WCAG-compliant builds with real cross-browser/device QA ✅ State management (Redux/Zustand, TanStack Query) and polished interactions with Framer Motion ✅ Automated testing with Jest and Playwright to keep regressions out of production ✅ REST API integration, auth flows, and Stripe (subscriptions, checkout, webhooks, usage-gated billing) ✅ Full-stack range with Node.js/PostgreSQL when a project needs it ✅ Figma-to-code handoff, design systems, and reusable component libraries How I work: I QA my own builds across desktop and mobile before calling anything done. I communicate clearly on your tool of choice, hit milestones on time, and I'm upfront if a project isn't the right fit rather than wasting your time. If you need a frontend engineer who can turn an AI feature idea into a production-ready product, let's talk.

If your business is losing customers to a clunky website, I fix that. When Pelumi's team brought me in to rebuild their platform, they saw a 1,400% increase in transaction volume driven entirely by a smoother, more seamless payment experience. That's the kind of result I'm hired for. SaaS founders and product teams hire me when they need a Full Stack Developer who can own a system end-to-end, not just write code but diagnose what's costing them users, fix it, and build the architecture to support what comes next. On the backend, I build with Node.js, Nest.js, PHP, and Laravel. On the frontend, React and Next.js. The glue between them is clean API design, RESTful APIs, third-party integrations, and data-driven systems built around MySQL and PostgreSQL. I also translate Figma designs to production-ready interfaces with Tailwind, HTML and CSS; pixel-accurate, responsive, and fast. Here's where I add the most value: — Your Stripe, checkout or payment flow is leaking conversions and needs a backend overhaul. — You're building a SaaS platform with multi-role access, authentication, and structured business logic. — You need a full-stack developer who can take a feature from Figma to deployed API without handholding. — You have a Next.js or Node.js codebase with performance problems or broken builds (I recently resolved complex build errors for a client and delivered clean, stable code to GitHub within the same engagement). — You're building an MVP and need someone who makes architectural decisions that won't trap you six months from now. Victor (Software Engineer) described the experience: the application went from broken to fully functional and stable, with clean, well-structured code delivered throughout. Anointed noted improved page load performance, secure authentication, and a streamlined checkout — all on the same project. I work with a backend-first mindset. That means I think about scalability, data integrity, and API structure before I write a line of frontend code. Systems I build are meant to grow with your business, not get rewritten when you hit traction. If you have a web application that needs to work harder for your business, let's talk.

Hi there 😊 I’m a Front-End Developer specializing in React and Next.js. I build marketplace platforms, SaaS dashboards, and product frontends that need more than just good visuals, especially apps with authentication, payments, dashboards, and smooth user flows. My work covers responsive UI, API-driven features, Supabase authentication, Stripe integrations, multi-step forms, and polished frontend architecture built for real use, not just demos. I run every project I take full ownership of through Google Lighthouse and PageSpeed Insights to test for SEO, Accessibility, and performance, aiming for a minimum score of 90%. I also take the delivery process seriously. I send updates before clients have to ask, flag blockers early, and stay clear about scope, progress, and timelines, so there are no surprises on either side.

I help businesses build, fix, and scale modern web applications with zero downtime. Whether you need a Next.js app built cleanly from scratch, complex API integrations, or critical bugs fixed in production, I step in to move your project forward. With 7+ years of engineering experience, I leverage modern web ecosystem tools and AI-assisted workflows to ship high-quality updates faster than traditional developer setups. Most clients hire me for one of three reasons: - They need a new web app or MVP built properly from the ground up. - An existing application is broken, slow, or has an uncompleted feature backlog. - They need a reliable, independent developer who can sync with an existing team and ship clean work immediately. My Core Technical Stack: - Frontend: React, Next.js (App Router), TypeScript, Tailwind CSS - Backend & DB: Node.js, NestJS, PostgreSQL - Cloud & DevOps: AWS, Vercel, API & Payment Gateway Integrations What I bring to your project: I care deeply about clear communication, technical reliability, and solving the actual business problem, not just writing lines of code. If a requirement is unclear, I ask targeted questions before building. If I spot a more efficient architecture or a security gap, I present a clear solution. If you need a developer who takes absolute ownership, communicates transparently, and helps unblock your product, let's chat about your project.
